Study these topics in order, and remember them
These questions are free to read. The app is the paid part, and it covers the whole exam rather
than stopping at Prelims: 83 Prelims topics, 34 Mains topics across 5 papers, the
interview, and 19 Bihar-specific topics — 94 chapters in reading order, each with a brief
on how the examiner asks it. ₹199 for a month, or ₹499 until your attempt is done — which is the one
to take if your exam is close.
